title = "Chemical potential shift, density of states and Fermi surfaces in overdoped and underdoped La2-xSrxCuO4",
abstract = "We have made photoemission studies of La2-xSrxCuO4 (LSCO) and found the following: (1) suppression of the chemical potential (μ) shift for small x indicates a breakdown of the Fermi-liquid picture in the underdoped regime and suggests the opening of a pseudogap; (2) valence band spectra have indeed shown a pseudogap whose magnitude increases with decreasing x, simultaneously the density of states (DOS) at μ diminishes; (3) ARPES measurements have revealed changes from an electron-like Fermi surface in the overdoped regime to a hole-like one in the underdoped regime.",
